KA-9003

SMART BIAS TEE

The Kaelus KA-9003 provides a flexible Smart Bias Tee solution allowing for AISG and DC to be placed onto a feeder at the bottom of the tower or extracted from the feeder at the top. Operating across all the cellular frequency bands the KA-9003 provides the following additional benefits

FEATURES

  • Primary surge protection limits the voltage let-through from the feeder to the DC port
  • Available in top of the tower or bottom of the tower applications
  • Variable connector configurations to allow for different installation techniques and scenarios
  • IP67 for continuous outdoor operation
